AI-Powered supplier vetting

SummaryThe supplier operates in electrical power facilities and equipment, including electrical instruments, meters, electronic and electromechanical components, repairs, and transformer manufacturing. It reports ISO9001, ISO14001, ISO45001, and CE certifications, with documented corrective-action, complaint-handling, and finished-product inspection procedures. Its innovation and customization capabilities are comparatively strong: it provides ODM, multiple customization options, has introduced new products within the past year, offers an SDK, and provides OEM services for well-known brands. However, the supplier reports no inventory capacity, overseas warehouse, overseas showroom, overseas agents or branches, and no valid contract with associated subcontractors. Export experience is limited to two years, with exports representing 11%–20% of total sales. Financial records are indicated for 2020–2022, but no substantive financial performance details are provided.

Supplier typeThe supplier is a manufacturer and seller in the electrical equipment sector, covering power facilities, electrical instruments and meters, electronic and electromechanical components, repairs, and transformer manufacturing. This supports classification as an electrical equipment manufacturer with related sales and service activities.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 management-system certifications, as well as CE product compliance certification. These explicitly documented certifications indicate coverage of quality, environmental, occupational health and safety, and product compliance requirements.

After-Sales capabilityThe supplier has documented corrective and preventive action procedures and complaint-handling procedures with follow-up records. However, it reports no overseas agents or branches, no overseas warehouse or showroom, and service coverage in zero countries, so the evidence supports process capability but not broad overseas service reach.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and has an available SDK. It also supports customization from samples and designs, full customization, minor customization, and flexible customization, indicating explicit product-development and technical-support capability.

Production capacityThe supplier identifies transformer manufacturing and other electrical-equipment production activities, uses standardized finished-product inspection instructions, and maintains quality assurance in quality-control processes. However, it reports no inventory capacity and no valid contract between the factory and associated subcontractors, creating limitations in stock availability and documented subcontractor management.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad service range appears in two slices, providing direct evidence of extensive customization capability.

Client casesThe supplier reports providing OEM services for well-known brands, which is evidence of experience serving recognized-brand customers. No specific customer names, project details, order scope, or performance outcomes are provided, so the depth of customer-case evidence is limited.

Product Q&A

Q:What is a Transformer Turns Ratio Tester used for?

It is used to measure the turns ratio of power and distribution transformers, verifying that the ratio between primary and secondary windings matches the nameplate value, and to detect shorted turns, open windings, incorrect tap changer positions, or wiring errors.

Q:How does a turns ratio tester work?

It applies a low-voltage AC signal (typically 10-40V at 50/60Hz) to the high-voltage winding, measures the induced voltage on the low-voltage winding, and calculates the actual turns ratio by dividing the primary voltage by the secondary voltage.

Q:Can it test both single-phase and three-phase transformers?

Yes, most ratio testers support both types. For three-phase transformers, the tester sequentially applies voltage to each phase (or all phases simultaneously in advanced models) and can also determine the vector group and phase displacement.
